It's not just running both - it's offering both as currently registering
these fatures is mutally incompatible.
For sure we would like to offer both, but as mentioned before, this will
require blk layer instrumentation and ib_core instrumentation to some
pipeline_mr or something like that.
We are interested in doing this IO path but doing all in 1 series
doesn't sounds possible.
First we would like to have at least the mutual exclusive solution since
there are users that may want only one type of acceleration.
re-designing, both blk layer and ib_core for the PI + CRYPTO case in
this series is not feasible IMO.
